LC1007
LC1007.The horizontal coordinates were scaled from a topographic map and have
LC1007.an estimated accuracy of +/- 6 seconds.
LC1007
LC1007.The orthometric height was determined by differential leveling
LC1007.and adjusted by the National Geodetic Survey in June 1991.
LC1007
LC1007.The geoid height was determined by GEOID99.
LC1007
LC1007.The dynamic height is computed by dividing the NAVD 88
LC1007.geopotential number by the normal gravity value computed on the
LC1007.Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45
LC1007.degrees latitude (g = 980.6199 gals.).
LC1007
LC1007.The modeled gravity was interpolated from observed gravity values.
